imn-s-hfo, the best place for drylock is on the shelf in the apron/vest store,,, thoroseal is a good product used in the right situation,,, nothing works well IF you use anyone's product incorrectly,,, there's nothing you can apply inside to stop an exterior leak - if there were, we pro's would be using it ! kthere are materials that can be applied to interior surfaces to stop leaks from appearing inside however the damage will still be taking place inside the walls.
dick - what happened to the bugatti veyron ? still in the shop ??????
